Regions

North Columbia, South Columbia, Clearwater, Esplanade, Jordan, North Monashee, North Selkirk, Shuswap, Badshot-Battle, Central Selkirk, Goat, Gold, Retallack, Whatshan.

Start your day early and watch the crust closely.

As it breaks down, reduce your exposure to avalanche terrain.

Confidence

Moderate

Avalanche Summary

Wet loose avalanches have been occurring on steep slopes facing the sun. Mostly small, but some large avalanches (size 2 to 3).

Snowpack Summary

A thin surface crust is expected to cover up to 25 cm of recent snow at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes, where buried weak layers may still be present.

Saturday

Mix of sun and cloud. 10 km/h variable direction ridgetop wind. Treeline temperature 7 °C. Freezing level 2700 m.

Sunday

Mix of sun and cloud. 10 km/h northwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2500 m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
